6 Claims.

This invention relates to the coiling of continuous strip metal, andparticularly to apparatus or means for determining the time required forcoiling the same.

It is the general object of the present invention to provide an improvedapparatus or means whereby the time that it is required to coil stripmetal on a take-up block after it has been rolled or otherwise processedcan be quickly and conveniently ascertained.

It isanother object of this invention to provide an improved apparatusor means of determining the time for coiling continuous strip metalwhich is not only simple and inexpensive in its construction and use,but an apparatus which can be easily incorporated with existingequipment at a minimum expense.

It is a further object of the invention to provide an improvedelectrically controlled appae ratus or means for determining the timefor coiling continuous strip metal which is controlled by the stripitself and is substantially fool-proof, and yet an apparatus whichaccurately records the coiling time.

Various other objects and advantages of this invention will be moreapparent in the course of the following specification and will beparticularly pointed out in the appended claims.

In the accompanying drawing, there'is shown for the purpose ofillustration, one embodiment which our invention may assume in practice.

In the drawing:

Figure 1 is a plan view of rolling mill and coiling device showing theimproved timing apparatus of our invention incorporated therewith;

Figure 2 is a side elevation of Figure 1;

Figure 3 is an enlarged section taken on the line I[IIH of Figure 1;

Figure 4 is a section taken on the line IV-IV of Figure 3; and

Figure 5 is a diagrammatical view of the wiring arrangement.

- Referring more particularly to the drawing, the

improved apparatus of our invention is shown incorporated with aconventional mechanism for coiling strip metal which consists generallyof a base or frame 2 having a cylindrical metallic coiling block 3rotatably mounted thereon. The block 3 is adapted to coil continuousstrip metal as it is delivered thereto and is adapted to be rotated byany suitable means (not shown). There is arranged forwardly of the baseor frame 2 and the coiling block 3, a cold rolling mill, and there isshown in the present instance for the purpose of illustration only thework rolls 4 thereof.

According to the present invention, there is disposed in a laterallyextending groove or slot 5 arranged in the periphery of the cylindricalblock 3, a metallic insert contacting member S having a projectingportion or' segment I arranged therewith preferably on the inner endthereof. The insert member 6 extends substantially through the width ofthe block 3 preferably flush with the outer face thereof, and isinsulated therefrom by means of an insulating material 8 which ispreferably made of fiber, rubber or any other suitable material andwhich is positioned between the insert member and the walls of thegroove 5 in the block 3.

There is suitably arranged preferably in the vicinity of the coilingmechanism, an electrically controlled recording instrument 9. Thisinstrument may be any of the known conventional types, but it ispreferable that an Esterline-Angus graphic instrument be provided. Suchan instrument consists generally of a rotatable cylinder which isadapted to hold a paper chart and which is driven at a constant speed bya clock mechanism. There is provided a pen which rests on the chart andwhich makes a continuous straight line on the same as the cylinderrevolves, as long as the pen is not moved. The pen is controlled byelectromagnets and when the same are energized, the pen is caused to bemoved so as to make a mark on the chart substantially perpendiculartothestraight continuous line, and it is returned to its normal positionusually by means of a spring. Therefore, each electric impulse whichenergizes the electromagnets will be recorded on the chart of theinstrument. The instrument, of course, is suitably connected to asuitable source of power (not shown) to operate the same.

One side of the instrument is connected to the base or frame 2 of thecoiling mechanism by means of the line Ill and the other side of therecording instrument is connected preferably to a contact finger l2 bymeans of line 13. The ,contact finger I2 is preferably mounted on aninsulating block I which is suitably arranged preferably on the side ofthe frame 2 directly opposite the projecting portion or segment 1carried by the insert member 5.

The improved apparatus of my invention functions in the followingmanner. The continuous strip of metal S is fed from the pay-off reelthrough and between the cold working rolls I and delivered to thecoiling block 3. At the start of the coiling operation of any particularstrip, the same is directed around the cylindrical coiling block 3 so asto make the first or inner convolution of the coil. It will thus be seenthat this first convolution of the metallic strip contacts both theinsert member 6 and the block 3 thereby completing one portion of anelectric circuit therethrough. That is to say, an electric circuit iscompleted through the insert member 8, the first convolution of thestrip S, the block 3, the frame 2 and the line 59, to the recordinginstrument 9. After the first convolution of the strip has been disposedaround the block 3, the projecting portion 7 of the insert member 6strikes or contacts the contact finger i2 upon each revolution of theblock. Thus, it will be seen that when the projecting portion '1 strikesthe contact finger E2, the other portion of the electric circuit iscompleted, namely through the contact finger l2 and the line E3, to therecording instrument ti, thereby energizing the electric magnets of theinstrument which in turn move the pen once each revolution of the block.Thereafter, the time for completely coiling the strip of metal on'theblock 3 can be readily ascertained upon inspection of the chart of therecording instrument. After the coiling of the strip has been completed,the coiled strip is removed from the block thereby breaking the circuitbetween the insert member 6 and the block 3. any further rotation of theblock 3 will not be recorded by the recording instrument as there isthen not a complete electric circuit.

The improved apparatus of our invention has been shown incorporated withcoiling mechanism for coiling strip metal as it is delivered. from a.

cold rolling mill, but it will be understood that it may be used inconnection with a coiling block for receiving and coiling the metal fromany other machine or process during the manufacture of the strip. Alsothe improved apparatus of our invention may be incorporated with acoiling mechanism for coiling wire, rod, or other continuous lengthmetallic materials.

While we have, in this application, specifically shown and described oneembodiment of our invention, it will be understood that this embodimentis merely for the purpose of illustration and description, and thatvarious other forms may be devised within the scope of the invention, asdefined in the appended claims.
